Patented Sept. 6 1932 ALFRED H. LENT, 0F GAPITOLA,,CALIFORNIA ENGINE noon VENTILATOR Application filed October 4, 1929, Serial No. 397,432.. Renewed January 18,1932.

This invention relates to improvements'in the ventilating means provided in the engine hoods of motor vehicles such as automobiles, airplanes and motor boats.

An object of the invention is to provide a ventilating means of the character descrlbed which will permit of ventilation of the engine hood in a particularly efiicient manner while at the same time lending itself to a fanciful and ornamental characterizatlon which is symbolic of speed, grace and power.

Another object is to provide a ventilator of the character described in which the apparatus is adjustable to vary the ventilation effect as desired to suit the weather and engine temperature conditions at hand.

The invention possesses other ob ects and features of advantage, some of Which, with the foregoing, will be set forth in the following description of the preferred form of the'invention which is illustrated in the drawing accompanying and formin part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention as set forth in the claims. Referring to the drawing, Figure 1 represents a fragmentary side elevation of an automobile showing the engine hood provided with the ventilating means of the invention.

Figure 2 is a horizontal sectional View taken on the plane of line 2-2 of Figure 1.

Figure 3 is a vertical sectional view taken on the plane of line 3-3 of Figure 1.

Figure 4 is a fragmentary vertical section of a slightly modified form of theinvention. v

In the present embodiment of the invention as shown in detail in the accompanying drawing, the engine hood 5 is provided with three ventilator units 6 but any number of said units may be provided, as desired.

One way of carrying out the invention con- I sists in forming elongated vent openings 8 in the sides of the hood and providing in any suitable manner on said hood a plurality of deflector strips 9 or plates which extend -in front of and conceal said openings with out closing'them. In Figures 1, 2 and 3 the strips .9 are separate pieces and are suitably aflixed to the hood whereby they overlap without actual contact with one another, and thus effectively conceal the openings while leaving sufiicient ventingspace between one another. 2 However, as shown in Figure 4; the strips 10 may be formed integral with the hood, in the customary manner, although the first form lends itself more readily to the highly desirable spread-wing appearance. I

The strips 9 or 10, as.tl1e case may be, are preferably and in any suitable manner made to simulate feathers whereby to present a wing appearance, it being noted that the said strips are graduated in] length like wing feathers, aspect. 1

. Arranged in overlying relation to certain ends of'the ventilator strips 9, and openings 8,0f eachset 6, is a deflector plate 11' which serves as a ventilation regulating means, and owingto its location at the front ends of the strips 9, veryreadily lends itself to a characterization simulating the body or inner end portion of a wing. Consequently the plate 11in any suitable manneris made to simulate said portion of a wing. This may, as shown, include the formation of fiutes'12'which being concave on the inner side. of the plate permit of ventilation through those portions of the openings 8 which lie under the plate.

Preferably the plate 11 ishinged as at 14 to swing on a vertical aXis with its forward to give the pointed or wing-tip m cuties:

tend outwardand rearward fromthe hinge point, the 'pla-te 8, due to the rush of air past it, creates a vacuum adjacent to its edges and thus permits of. a more rapid and effective ventilation through the openings 8 than when said plate lies in normal position substantially paralled with the side of the hood. Thus, the ventilation action of the openings Sand strips 9 is regulatedby the hinged plate 11 and the desired ventilation effect maybe readily obtained to suit different weather conditions and engines.

ornamental wing appearance is enhanced and the ventilation action is likewise improved.

I claim:

1. In a ventilator for the engine hood of a motor vehicle, said hood having a vent opening therein, a deflector strip disposed in outwardly spaced relation to said opening, and a deflector plate adjustably supported on the hood and being adjustable from a position lying over portions of the strip and opening to a position extending outward and rearward from said portions of the strip and opening.

'2. In a ventilator for the engine hood of a motor vehicle said hood havin a vent 0 en- 7 1':

ingtherein, a deflector strip disposed in outwardly spaced relation to said opening, and a deflector plate adjustably supported on the hood and being adjustable from a position lying over portions of the strip and opening to a position extending outward and rearward from said portions of the strip and opening,said plate and strip being of such a form and appearance as to conjointly simulate the wing of a bird.

3. In a ventilator for the engine hood of a motor vehicle, said hood having a vent opening therein, and a plurality of deflector members carried by the hood and lying in outwardly spaced relation to and concealing said opening, said members being disposed in overlapped relation and as a group being arranged to simulate the wing of a bird.

4. In a ventilator for the engine hood of a motor vehicle, said hood havin a vent opening therein, and a plurality of deflector members carried by the hood and lying in outwardly spaced relation to and concealing said opening, said members being disposed in overlapped relation and'as a group being arranged to simulate the wing of a bird, and one of said members being adjustable to vary the ventilator action through said vent opening.

5. In a ventilator for the engine hood of a motor vehicle, said hood having a vent there in, of a plurality of deflector members each arranged with an edge thereof in outwardly spaced relation to said vent, one of said members overlying the remainder of said members. v

6. In a ventilator for the engine hood of a motor vehicle, said hood having a plurality readily lend themselves to the formation of jointly'simulating the wing of a bird.

In testimony whereof I have hereunto set my hand at Oakland, California, this 19th day of September,1929.

ALFRED H. LENT.
